Earlier today, an ambulance was called to Savchenko during the hearings of her case after she said she was feeling unwell and was having chest pain. However, medics decided not to hospitalise Savchenko saying she could take part in the hearings.

Savchenko, 33, has been in custody in Russia since July 2014.

Russian investigators say that Savchenko, the gunner of a Mi-24 helicopter, joined the notorious Aidar battalion during combat operations in the much-troubled Lugansk region of eastern Ukraine last June.

Noting the position of a filming crew of the Russian State Broadcasting Company and other civilians, she allegedly reported the data to mortar-equipped personnel who fired on the crew and the civilians. As a result, correspondent Igor Kornelyuk and sound engineer Anton Voloshin were killed.
